DK-TM4C129X
– Slave generates interrupts when data has been transferred or requested by a master or when
a START or STOP condition is detected
■ Master with arbitration and clock synchronization, multimaster support, and 7-bit addressing
mode
■ Efficient transfers using Micro Direct Memory Access Controller (µDMA)
– Separate channels for transmit and receive
– Ability to execute single data transfers or burst data transfers using the RX and TX FIFOs in
the I
